Client shutdown just after opening "Tech Tree"

My client shuts down 3 to 4 times a day, and it seems to be within a few seconds of me opening "Tech Tree" while mousing over tanks. It doesn't always happen, but I've noticed this trend and have confirmed it over my last 5 uncommanded client shutdowns.

I don't want to hijack this thread, but I've been having the same problem (no mods installed, BTW...not even a premium tank, though I'd love to get my grubby, oil-and-gunpowder stained mitts on the Super Pershie...). When you say "use the 306.97 nvidia drivers" what exactly do you mean? My gaming comp specs are as follows:

so are these drivers an up or downgrade? Sorry again for hijacking this; I'm not very tech-savvy, especially for a young teenager! (Though, since I love WWII armored vehicles, that's not that much of a surprise...)

Interesting, I see the same thing. However, I don't feel like changing video drivers since no other app has a problem. It only seemed to start happening with 8.4 for me. But I cope by not using the tech-tree much, or if I do then I don't mouse-over anything unless I want to buy it. Don't know if it's coincidence but it's only ever mouse-over-crashed on the russian line. Odd.
